Relatives mourn as they lift portraits of family members they lost in the collapse of a mountain of trash at a garbage dump, during a funeral service held at the Gebrekristos church in Addis Ababa, Ethiopia Monday, March 13, 2017. The death toll reached more than 60 on Monday from the collapse at the dump on the outskirts of the capital, according to the state-affiliated Fana Broadcasting Corporate, as relatives waited for news of the dozens of people said to be missing.

ADDIS ABABA, Ethiopia — Ethiopians have started observing three days of national mourning after a deadly landslide in which scores were killed.

The death toll is at least 72 following the collapse on Saturday of a mountain of garbage in a landfill outside Ethiopia's capital, Addis Ababa.

Many victims were women and children trapped when makeshift mud-and-stick homes inside the Koshe landfill were buried in debris.

It was not clear how the collapse occurred.
